IMPROVEMENT IN JACKS FOR CARRIAGE-SPRINGS.

The Schedule referred to in these Letters Patent and making part of the same. I

To (177 n'lzomit may concern:

distinct article of manufacture, it being the design to furnish the same' to the market forthe convenience of carriagc-nntkers, bywhom it is to be employed as a connection between side'springs and the bolster or rear axle.

.11] order that others skilled in the art to whjchmy invention appertains may be enabled to fully understand and use thesame, I will proceed to describe it in connection with the accompanying drawing.

The device is formed or cast in one piece. It has an elongated eye, a, which, in connection with a buckle or other appliance, is intended to form a joint connection for the end of the side spring of a vehicle. The eye a surmounts a neck, 6, rising from the rest or hearing part c, which unites the arms 41 d, which embrace either the bolster or rear axle, and which must,

before being applied thereto, have their ends threaded to receive nuts, whereby the device is firmly clamped upon said holster or axle.

c e are wings projecting laterally from 4 the neck I), and, being like the bearing part c concave on the under side,"they have the effect to extend or enlarge the bearing surface, the purpose being to. adapt the dc vice to remain more steadily and firmly in true position than the devices heretofore employed for the same purpose.

As hetbre stated, the device may be a special article of manufiwturc to be put on sale.

The threading of the arms (I d, and such finishing up as may be needful, can be perfin'mcd by the coachmakers or others wheuthe device is to be applied to the vehicle.

Having I-llllStleSCl'lbPd. my invention,

What I claim as new, and desire to secure by Letters Patent, is-

A jack or spring-holder having the wings a e or an enlarged bearing surface, substantially as and for the I purposedescribed,

The above signed by me this 21st day of January,
